  Stereoselective synthesis of α-hydroxycyclopropanecarboxylic acids

  摘要：

  Cyclopropanation of chiral alpha-alkoxy acrylamides derived from 1R,2S-ephedrine and alpha-keto acids provides cyclopropyl morpholinones with good diastereoselectivity. Removal of the ephedrine portion generates alpha-hydroxycyclopropane carboxamides which are readily converted to enantiomerically enriched alpha-hydroxycyclopropanecarboxylic acids.

  Enantioselective synthesis of α-hydroxy γ-butyrolactones from an ephedrine-derived morpholine-dione

  摘要：

  An ephedrine-derived morpholine dione is employed in the enantioselective synthesis of (S)-alpha-hydroxy- gamma,gamma-dimethyl-gamma-butyrolactone and (S)-alpha-hydroxy gamma-butyrolactone. A one-pot alkylation/allylation protocol for the stereoselective conversion of the dione to 2-alkyl-2-allyl morpholinones, key intermediates for alpha-alkyl-alpha-hydroxy-gamma-butyrolactones, is described.
